because they need to have blood in their wings to be able to fly

Tane Tomoko.

The wings. These are used to bring their blood up to temperature which flows through small capillaries within the wings. The butterflies open their wings to the sun to expose them to sunlight.

Yes you can, but if the horse has the 5th element coat before the Medusa's blood the wings will not show up. If however the horse has the Medusa's blood before putting the 5th element on the horse it will have visible wings.
